Lobelia Herb – Uses And Side Effects

Because lobelia has nicotine-like effects, some people have used it to help them stop smoking. Lobelia comes primarily from the dried leaves and tops of Lobelia inflata. The herb is named after the botanist Matthias de Lobel, a native of Lille, who died in London in 1616. It is an erect annual or biennial herb, 1 to 2 feet high; lower leaves and also flower are stalked, the latter being pale violet-blue in colour, tinted pale yellow within. Commercially, it is usually prepared in compressed, oblong packages, by the Shakers of New Lebanon for importation into England. The colour is a yellowish green, the odour irritating, the taste, after chewing, very like that of tobacco, burning and acrid, causing a flow of saliva. The powder has a greenish colour, but that of the seeds is brown, and stains paper with grease.

Common doses of lobelia

Lobelia comes as:

  • capsules (395 milligrams)
  • tablets (2 milligrams)
  • lozenges (1 milligram)
  • extract

Some experts recommend the following dose:

  • As a smoking deterrent, 0.5 to 2 milligrams in tablets or lozenges. The usual dose is 2 milligrams taken orally after each meal with 1/2 glass of water for no more than 6 weeks. Oral doses up to 8 milligrams have been used but caused significant stomach upset. Daily oral doses of beline (an alkaloid in the herb) exceeding 20 milligrams are considered poisonous.

Uses of lobelia

Lobeline, an active constituent in the lobelia plant, is very similar to nicotine in its effect on the central nervous system. Lobeline acts as a relaxant overall while also dilating the bronchioles (air passages), thereby increasing respiration and possibly helping the lungs. Specifically, lobelia may help to :-

  • As a smoking cessation aid
  • Asthma
  • Bronchitis
  • Muscle spasms
  • To induce vomiting

Side effects of lobelia

Call your health care practitioner if you experience any of these possible side effects of lobelia:

  • coughing
  • dizziness
  • fluid retention
  • nausea and vomiting (with higher doses)
  • palpitations
  • seizures
  • severe heartburn
  • stomach pain
  • sweating
  • tremors

Lobelia also may cause:

  • death (from respiratory depression and respiratory muscle paralysis)
  • increased blood pressure
  • respiratory slowing (with high doses) or stimulation (with low doses)
  • slow pulse

Interactions

Combining herbs with certain drugs may alter their action or produce unwanted side effects. Don’t use lobelia while taking drugs used for nicotine therapy.

Important points to remember

  • Don’t use lobelia if you’re pregnant or breast-feeding.
  • Don’t give this herb to children.
  • Be aware that an overdose of lobeline (an alkaloid in lobelia) causes such symptoms as an irregular heartbeat, extreme sweating, dizziness (from low blood pressure), muscle twitching, seizures, chills, and coma.
  • If you have liver or kidney problems, check with your health care practitioner before using this herb.
  • To help stop smoking, medical experts recommend smoking cessation programs, counseling, behavior modification, nicotine replacement, and other drugs instead of Lobelia.
  • Don’t use any product containing lobeline for more than 6 weeks because researchers have no information about long-term use.

What the research shows

Because it’s similar to nicotine, lobeline, an alkaloid in lobelia, has been used to help people stop smoking. However, no longterm data are available and no clinical trials have been done. Lobeline can cause more serious side effects than other smoking cessation treatments. Therefore, medical experts don’t recommend it.
